Abstract: Methods and apparatuses are provided for transmitting information about an omni-directional image based on user motion information by a server. Motion parameters are received from an apparatus worn by a user for displaying an omni-directional image. User motion information is generated based on the received motion parameters. First packing information corresponding to a user position is generated based on the user motion information. Second packing information corresponding to a position in close proximity to the user position is generated based on the user motion information. Third packing information is generated based on the first packing information and the second packing information At least one of the first packing information, the second packing information, and the third packing information is transmitted to the apparatus.
